To all whom it may conga-n:

Be it known that 1, Jaime 33am, mil-M811 of the United States, residing iJ-etioii; 1n

the county of TWayne and State of Michigan,

have invented new and useful Improvements in Die-Qasting Machines, of which the following is a specification.

This invention relates to va. die casting machine, particularly of that iypcin which the molten mes'zal is ejected from the meial pot through an outlet or mouth piece by an ere pelling plunger, operated manually or by pneumatic means. i

()ne object of bhe inve on is to provide a die casting machine having an outlet spout and mouth piece, together with a controlling valve of novel conei uction, whereby the metal may hedischarg fzii to cast either in horizontal position in from of the mouth piece or in a vertical position he neath the mouth piece.

A further ohj'eci of the invention to provide means whereby the plunger and valve may be simultaneonsiy operated to dis charge or cut oil the flow of the molten metal.

A further object of the invention is to provide a mouth piece or discharge nozzle having front aml bottom discharge'outlets and. a'btz'ich'ments whereby the machine may be quickly and. cmiveniently adapted for making castings of the character described and also to provide an attachment whereby the machine may be adapted for making vertical overlie-ail castings, the machine be ing thus rendered of ilfll.'("8z1l use in male mg the various kinds of easilngs in demanch A still, further object of the invention is to provide aiinouth piece and attach ments of the character forth whereby the machine may be converted to make any of the aforesaid kinds of castings in a ready, quick and convenient manner.

The invention consists of the features of construction, combination and arrangement of parts herein fully (iesci'ibed and claimed, reference heii'ig had izo accompanying drawings in which y Figure 1 a vertical section. in con h a die casting machine'emhoclving i tion, showing him outlets and valve In c posieion.

- which supports a ineltingpot 2 heated by a suitable burner 3. The metal isdischargec'i from ehe poi through a spent 01' conductor t which extends at its receiving engl into rifle" pot and is proviiiecl With a port 5' F02 the so flow of the metal thereinto. A plungeifl 6 operates in theverticai receiving; elm of the spout or conductor and may he been aiveclin any suitable .manner: AS shown in the present instance the change: stem/.7 e185 connected with a piston 8- Working. in. a cylinder 9, connected'hy suitable conohicoors i0 and 11 with avai e l2. The ,valvel controls the supply and exhaust of aiifi furnished from anv om'ii'nbld source of Le-inlet) supply toanclfroni the cylinder 9, by which the piston 8 iis-opei'atecl to projeci and re iu'actehe plunger. Instead of a pneumatically oper'aied plunger; any othei style of pneiunaizic feed, or pneumatic mechanical, 95 on manually actuated plunger feed mech- -,an. isn1.inay be employed.

have not (leemecl if necessary to show othef than certain types of feed; mechanism,

the feed. mechanism hroadly COHSIElGIGd, ioo co szfiiiutes part oi the present invention. The outei; or disc large end of the spout i)! conductor 4.- "ceiniinaies in a mouth piece 61 nozzle 13 having mpered chamber 1 communicating with a front discharge port o'r-outlet 15 and a threaded bottom socket or outlet 16. The port or outlet 15 is con- ,rolled by a sliding, dove-tailed cut off plate formed with a horizontal transverse passage 32 adapted to connect the discharge duct in the spout l with the outlet 15, and is also, provided with a vertical passage 33 117 movable in a dove-tailed guide way 18 and "provided with one or more discharge open ings 19. This late is adjustable to one position to cut 0; communication between the outlet and the opening or openings 19,

gwhen the mouth piece is not inuse or is leading downwardly from the passage 32 and communicating with the pocket 27 in the member 22, whereby the bottom outlet is also adapted to be placed in communication with the-duct in the spout l. When the valve 29 is turned to aout ch position,

1 device may employed for other than making front horizont'al castings, and is adjustable to a certain position in which the opening or openings 19 register with theoutlet 15 for the L5 discharge of metal in making fronthorizon- A. set screw or other suitable be employed to secure the plate 1'? in its described positions. I

The socket 16 is threaded .to receive a tal castings.

20 bottom outlet controlling device consisting of two parts, to wit, a plug or closure member 21 and a valve or controlling member 22. The plug or closure member has its body externally threaded to engage the threads of in which the passage 32 is out of register with the spout and outlet 15 the flow of the molten metal to either the front outlet or the bottom outlet is prevented, but when the valve is turned to a position in which its passage 32 registers with the spout and outlet 15, the apparatus is in condition for either front horizontal or underhead vertical casting, the discharge of the metal in one direction or the other being'controlled .by the cut off plate 17 and the cut off or controlling member 21.

The upper end of the valve 29 isintegral with a stem 3 1 and is provided with a cylindrical threaded portion 34: engaged by a split clamping nvt 35 resting upon a hard metal friction disk or washer 35 seated upon the top of the mouth piece 13, whereby the valve is adjustably supported andvmay be maintained in close engagement with its seat. The upper end of the stem 34. is arranged in proximity to the stem 36 of the air valve 12, the proximate ends of said. stems being connected by an operating lever 37 by which the two valves 12 and 29 may is provided at its upper end with a flange 26 .to'rest upon the top of the member 21, and is formed with a cavity 27 opening through its top and communicating at its lower end i 40 with ports 28 adapted to register with the grooves 25. When the plug or closure member 21 1s turned-up to a fully applied position, the grooves 25 are disposed so that they are out of register with the ports 28, so

that, the bottom outlet of the mouth piece or nozzle will be closed against the discharge of metal, while when said mouth piece or nozzle is turned downward to a predetermined extent the grooves 25- will be brought in position to communicate with-"the port's 28, when the member 22 is turned to a (irtain position by means of the controlling valve, so that the molten metal may be discharged through'the bottom outlet for under-head vertical casting.

The tapered controlling valve 29 fits with in the valve chamber 14:, and is adapted to be applied and removed through the hotn tom outlet. This valve is formed in its base with sockets 30 to receive pins or projections 31 on the member 22, whereby said member 22 will be coupled to the valve 29 for movement :thei ewith. f-The valve is I ranged in position be simultaneously turned to "feed and cut-oil positions.

When the valve 29 is in the position shown in Fig. 1, and the cut off devices 17 and 21 are adjusted as shown in said view, the spout is closed against the discharge of the metal while the plunger 6 is in raised or retracted position. Itit be desired to make a front horizontal casting, the plate .17 is adjusted to bring the discharge opening 19 into communication with the outlet passage 15 whereupon by turning the lever 37 in, the pntiper direction the valves 12 and 29 its willbe simultaneously opened, the plunger '6 being forced downward and expelling a charge of metal from the sprint and through the valve passage 32, outlet 15 and opening 19 into the die mold, which is suitably archarge of metal. U on then turning the lever 37 to its norma position, theflow of metal will. be cut oii' and the plunger retracted. If it should be desired to make a to receive the expelled vertical underhead casting, the out od 17 is adjusted to closed position, and the closure v to a predetermined member 21 unscrewed extent, so that when the lever 37 is again moved to open the valves 12 and 29,'the

member predetermined qdjuiggnents of the latter.

5. In a die (testing machine, the combination of a discharge spout a month ,piece connected. therewith and provided with front and bottom outlets, controlling membet-s for said outlets, a, valve for controlling communication between said s out and the respective outlets, and a, con uotor interchangeable with the valve for use upon th mouth piece, said conductor being provided with a discharge tube for over-head casting. In testimony whereof I afiix my signature in presence of two Witnesses.
